, DISPLAY APPARATUS.

To all whom it may 00ncern Be it known that I, KIl-I'EI Konm, a citizenof Japan, and a resident of the city of Seattle, in the county of Kingand State of Washington, have invented certain new and usefulImprovements in Display Apparatus, of which the following is aspecification.

My invention relates to apparatus of the above type, having moreparticular reference to signs, and has for a primary object theprovision of a novel construction including an apron which is adjustablefor obtaining an intermittent display of advertising or other suitablesubject matter.

With the above and other objects in view, to be referred to as mydescription progresses, my invention consists in the features ofconstruction, arrangements and combinations of parts hereinafterdescribed and succinctly defined in my annexed claim.

Referring now to the accompanying drawing, wherein like numerals ofreference indicate like parts throughout the several views: Figure 1 isa section of a display device constructed in accordance with myinvention, taken on line 11 of Fig. 2, with parts broken away. Fig. 2 isa cross sectional view taken on line 2-2 of Fig. 1, and Fig. 3 is afragmentary perspective, illustrating a slightly modified construction.

In carrying out my invention I provide an apron or flexible strip 1,connected with a roller 2, on which it is adapted to be wound, the saidroller 2 being provided with a gear 3 in mesh with a pinion 4, fixed toa drive shaft 5. As now considered, apron 1 has its free or lower endportion suitably weighted, as by a transversely disposed rigid member 6secured thereto and provided with end extensions 6 slidably engaged invertical guide grooves 7 in the adjacent end walls of a suitable casing8, having a sight opening 8', in its front wall, across which said apronis movable for the display of its contents therethrough. Drive shaft 5,is connected by belt 9 with a suitable reversible motor 6",

which latter is controlled, as hereinafter set forth, to drive shaft 5in opposite directions, and thereby, through gear 3 and pinion 4:,effect an alternate winding and unwinding of apron 1.

I preferably employ in conjunction with apron 1 a sign face 10, thelatter conveniently comprising one side wall of a hollow partition 11 ofeasing 8 and being ar- Specification of Letters Patent.

ranged at the inner side of the apron so as to be exposed when the apronis wound up and consequently withdrawn from the field of display. Bythis arrangement I am onabled to provide a construction, wherein signface 10 can be employed alone for reception of the display matter, orconjointly with apron 1, in the latter instance the said apron forming asecond sign face while in the former merely serving as a curtain.

For reversing the direction of rotation of motor 6", I have shown areversing switch 12, of a well known type, the same consisting of a pairof pivoted arms 15 connected by a bar 13, of insulating material, thesaid arms when switched moving alternately into engagement with contactsof respective leads 14, 14 of the motor, as shown and thus changing thedirection of the armature current. The end portions of bar 13 aresuitably extended and one thereof projects into the path of a cam strikepart 16, consisting of a projecting lug of member 6 and having itsactive face suitably inclined for effecting a shifting of the switcharms, as herelnbefore set forth, when apron 1 approaches the upper endof its limit of travel. A second strike part 16, movable simultaneouslywith strike part 16, but in a relatively reverse direction is adapted toengage the opposite end portion of bar 13 and thereby serve to controlthe reversing of the direction of travel of apron 1 as the latterreaches it other or lower limit of movements.

In producing a double sign, as shown, I provide a second apron 1 whichis movable across a si ht 0 enin 8 and over a si face 10, the latterconveniently consisting of the opposite side wall of partition 11. Apron1, which is identical in construction to apron 1, carries strike part16' on its bar 13, and is fixed to a roller 2, driven from shaft 5through a gear 3 of said roller meshing with pinion 1, the said roller 2controlling its apron to move the same simultaneously with apron 1, butin a relatively reverse direction.

In Fig. 3, I have shown a. slightly modified construction wherein theside walls of a partition 11 constitute transparent sign faces 10, 10between which suitable illuminating means, as 17, can be arranged.

Having thus described my invention what I claim as new, and desire tosecure by Let- 10 movement of said aprons, and means on said aprons eacharranged for operating said controlling means in a respective directionby and during movement of said aprons in one direction.

Signed at Seattle, Washington, this 24th 15 day of January 1911.
